Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504798, here are decompositions:

107 + 31504691 = 31504798
131 + 31504667 = 31504798
137 + 31504661 = 31504798
179 + 31504619 = 31504798
191 + 31504607 = 31504798
251 + 31504547 = 31504798
317 + 31504481 = 31504798
359 + 31504439 = 31504798

Showing the first eight; more decompositions exist.
